Abstract
The invention discloses an anti-falling protection device and an anti-falling protection system. The anti-falling protection device comprises a rope penetrating part, an extending part and a connecting part, wherein the rope penetrating part is provided with a first end and a second end and is suitable for a rope to penetrate through; the extending part is provided with a first end and a second end; the first end of the extending part is fixedly connected to the second end of the rope penetrating part; the connecting part is connected to the extending part and is suitable to be connected to an object to be protected through a safety belt. When the connecting part is applied with tensile force of component force opposite to the direction from the first end to the second end of the rope penetrating part, the tensile force applies moment to the anti-falling protection device, so that the anti-falling protection device is rotated. Therefore, when the object to be protected is fallen, the tensile force is generated for the connecting part and applies moment to the anti-falling protection device, so that the anti-falling protection device is rotated. Therefore, the rope penetrating part generates friction resistance on the rope penetrating through the second end of the rope penetrating part, so that the object to be protected is prevented from directly falling.
